What is the difference between a cohort study and a cohort sequential study?
What will be an ideal response?
A cohort study involves the study of a specific, well-defined population over time. The same group of people, but not necessarily the same individuals, provide data so the researchers can track changes from one wave to the next.
A cohort sequential design involves studying the same people over time, but at each measurement, a new group is brought into the study that is the same age as the original group was in the first measurement. At each measurement, every group that had been included is retained, but a new group with the same characteristics of the initial group at the beginning of the study starts participation.
